Cable shielding ring

The invention provides a cable shielding ring. The cable shielding ring comprises a shielding ring main body and a fixing assembly used for fixing the shielding ring main body on a cable; the fixing assembly comprises a connecting piece which extends to the outer side of the shielding ring main body; an auxiliary plate is mounted at the tail end of the connecting piece; the end surface of the upper side of the auxiliary plate is a curved surface which protrudes outwards, and the end surface of the lower side of the auxiliary plate is a horizontal plane; and the auxiliary plate is used for generating an air pressure under the action of airflow. The connecting piece is provided with the auxiliary plate with the upper end surface being the curved surface and the lower end surface being the horizontal plane; under the condition of ambient wind, the auxiliary plate can be rotated to adjust a stress state of the cable shielding ring; and through additional lifting force, the vibration amplitude is improved and the
